Description
Technical field:
The utility model relates to a kind of door lock assembly of haberdashery and hardware class, and is especially relevant with a kind of improvement of anti-picking device of security door.
Background technology:
The doorframe and the door leaf of common in the market security door are pressed into by steel plate, close its doorframe and door leaf applying behind the door, between door leaf and doorframe, leave the gap, although have theftproof lock to insert locking at door leaf and doorframe junction, but the dead bolt that inserts lockset with ripping bar when stealer is easy to make the distortion of doorframe and door leaf during with the lock latched position, causes the disengaging of dead bolt and lock and doorframe, security door is pried open easily, greatly reduces theftproof performance.And that side with the anti-theft door frame applying that lockset is not installed of existing antitheft door leaf generally is hinged with articulated mountings such as loose-leaves with anti-theft door frame, can rotate and open around pin joint so that lockset is opened the antitheft door leaf in back, therefore stealer can be selected to destroy pin joint with the method for sled or saw, thereby door leaf and doorframe are broken away from.
Technical scheme:
The utility model provides a kind of anti-picking device of improved security door, and it is simple in structure, can improve the pick-proof ability of security door greatly, and relative cost is lower.
For reaching above-mentioned purpose, the utility model adopts following technical scheme:
The antitheft door leaf of a kind of anti-picking device of improved security door, anti-theft door frame and lockset, antitheft door leaf is articulated in anti-theft door frame, two side panels of antitheft door leaf and anti-theft door frame are fitted, a side panel is provided with lockset, it is characterized in that: the side panel of not establishing the antitheft door leaf of lockset convexes with a fin to anti-theft door frame, position corresponding with described fin on the anti-theft door frame is provided with a groove, and fin is placed in the groove; Be the center of circle, pin joint with the pin joint to the fin apart from pin joint distance more farthest be that circle and the groove that radius forms has only an intersection point, and this intersection point be positioned at respect to pin joint and pin joint to the fin for the line of pin joint some formation farthest on the groove surface away from antitheft door leaf one side.
Above-mentioned technical characterictic not only will destroy pin joint in the time of stealer will being pried open have the antitheft door leaf side of pin joint, also will destroy fin, has increased the destruction difficulty greatly.And this fin does not influence the switch of antitheft door leaf fully, promptly can be by the groove blocking on the anti-theft door frame yet.
Antitheft door leaf and outer antitheft door leaf in being provided with in the anti-theft door frame, inside and outside antitheft door leaf is hinged on the anti-theft door frame respectively.
The end of the side panel of the described antitheft door leaf gusset that stretches out in addition is attached on the anti-theft door frame.
Extend a thin plate before the side panel lateral of described outer antitheft door leaf, the end of this thin plate inwardly protrudes out a fin, the anti-theft door frame that is mated forms a groove at the fin place, and fin inserts in the groove, and described lockset is arranged on the inside at fin and groove fit place.
The end of side panel of the antitheft door leaf fin that directly stretches out in described, the anti-theft door frame place of being mated is provided with a groove, and in the fin insertion groove, described lockset is arranged on the inside at fin and groove fit place.
The end of described gusset is square or arc.
Above-mentioned fin can be the strip rib, also can be the column fin, cooperates the groove of respective shapes.
The lockset of external door all was arranged on the inside at fin and groove fit place in above-mentioned technical characterictic made, and the thief can't prize lockset, and it is not only simple in structure, easy to operate, and the pick-proof ability improves greatly, and is safe and reliable.

Embodiment:
Embodiment of the present utility model such as Fig. 1 Fig. 2 and Fig. 3 and shown in Figure 4, a kind of anti-picking device of improved security door, comprise antitheft door leaf 1, anti-theft door frame 2 (comprises interior anti-theft door frame, outer anti-theft door frame) and lockset 3, antitheft door leaf 1 is articulated in anti-theft door frame 2 by loose-leaf 8, two side panels of antitheft door leaf 1 and anti-theft door frame 2 are fitted, a side panel is provided with lockset 3, the side panel of not establishing the antitheft door leaf 1 of lockset convexes with a fin 11 to anti-theft door frame 2, position corresponding with described fin 11 on the fin anti-theft door frame 2 is provided with a groove 21, and fin 11 is placed in the groove 21; Fin 11 can be the strip fin, cooperates long recess 21, also can be spot-like projections, fit.
With pin joint 8 be the center of circle, pin joint 8 to the fin 11 apart from pin joint 8 farthest 1: 111 distance be that the circle 82 that radius forms has only an intersection point 211 with groove 21, and this intersection point 211 be positioned at respect to pin joint 8 and pin joint 8 to the fin 11 for pin joint 81: 111 line 81 that forms farthest on the groove surface 21 away from antitheft door leaf 1 one sides.Because antitheft door leaf 1 is outwards opened, the antitheft door leaf 1 that has satisfied above-mentioned requirements is when outwards opening, and fin 11 just can not run into groove 21, and fin 11 does not influence the unlatching closure of antitheft door leaf 1 fully.
Described antitheft door leaf 1 inwardly protrudes out a fin 4 with the end of the side panel that doorframe 2 is fitted, be provided with a groove 5 with described fin 4 correspondence positions on the anti-theft door frame 2, described fin 4 is just stretched in the groove 5, and described lockset 3 is arranged on the inside at fin and groove fit place.The end of the side panel of described antitheft door leaf 1 gusset 6 that stretches out in addition is attached on the anti-theft door frame.Extend a thin plate 7 before the side panel lateral of described external door leaf, the end of this thin plate 7 inwardly protrudes out a fin 4, the doorframe that is mated forms a groove 5 at fin 4 places, and fin 4 inserts in the groove 5, and described lockset 3 is arranged on the inside at fin and groove fit place.The end of side panel of the door leaf fin 4 that directly stretches out in described, the doorframe place of being mated is provided with a groove 5, and in the fin insertion groove, described lockset 3 is arranged on the inside at fin and groove fit place.The end of described gusset can be square or arc, makes the profile of door more attractive in appearance.
Adopt technique scheme, because the lockset of interior external door leaf all is arranged on the inside at fin and groove fit place, the thief can't prize lockset, even the thief destroys the pin joint of the antitheft door leaf side that lockset is not installed, also must destroy the fin in the groove, therefore have two-layer tamper-resistant function, it is not only simple in structure, easy to operate, and the pick-proof ability improves greatly, and is safe and reliable.
